Strait of Hormuz
Strait of Hormuz: Iranian control claims and disruption risk at a vital oil and gas shipping chokepoint
The Strait of Hormuz is a major maritime route for oil and gas exports. Its traffic includes oil tankers and other commercial vessels, with Iraq, Iran, Saudi Arabia and the United Arab Emirates linked to its use or security. US-led maritime activity and NATO planning have focused on keeping navigation open.
The supplied reporting describes a disrupted operating environment. JMIC rates the threat as SEVERE, while confirmed crossings have fallen 19.5% to 95 and traffic remains below pre-war levels. Reports say a closure on 4 March 2026 stranded oil and LNG exports; an 8 April ceasefire later came under strain after Iran resumed its blockade. The record combines current claims with older, inconsistently dated reporting.
- Iran has granted passage to some Iraqi oil tankers, showing that access can be managed selectively.
- JMIC continues to rate the Strait of Hormuz threat level as SEVERE.
- Confirmed crossings reportedly fell 19.5% to 95, with ordinary commercial traffic below pre-war levels.
- A reported 4 March 2026 closure stranded oil and LNG exports and drove higher global energy prices.
- US Navy destroyers crossed on 11 April 2026 and were challenged by Iran's IRGC naval forces.
- Saudi Arabia and the UAE are expanding pipelines and infrastructure intended to bypass the Strait.
